Getting Started

Create KEYs for third party APIs

Voice assistant uses third party APIs for speech recognition, building routes and weather forecasting.

• VK ASR API: free API for speech recognition.
• Yandex SpeechKit: paid API with a free period of 2 months for speech recognition.
• Yandex GeoCoder: API for current location and building routes (free for non-commercial use)

Third party tools

• Since the speech recognition APIs accept the ogg audio format, you will need to install the universal media converter to convert the audio FFmpeg.
• Using library Qt-Secret for encrypting API keys.
